3. Pre-Algebra Rational Numbers Lesson 4-6 A fast sports car can accelerate from a stop to 90 ft/s in 5 seconds. What is its acceleration in feet per second per second (ft/s 2 )? Use the formula a =, where a is acceleration, f is final speed, i is initial speed, and t is time. f – i t a = f – i t Use the acceleration formula. The car’s acceleration is 18 ft/s 2. 90 – 0 5 Substitute.= 90 5 Subtract.= 18=Write in simplest form. Additional Examples
